Title:
PEEL STRENGTH-IMPROVED SEMI-CONDUCTIVE SHIELDING MATERIAL, PREPARATION METHOD, ARTICLE, AND CABLE
Document Type and Number:
WIPO Patent Application WO/2024/045340
Kind Code:
A1
Abstract:
The present disclosure relates to a peel strength-improved semi-conductive shielding material, a preparation method, an article, and a cable. The peel strength-improved semi-conductive shielding material is prepared from the following raw materials in parts by mass: 58-68 parts of a matrix resin, 27-34 parts of conductive carbon black, 1-5 parts of maleic anhydride grafted polyethylene, and 0.4-2.2 parts of a cross-linking agent. Low-density polyethylene resin and ethylene-acrylic resin in the matrix resin have good interfacial compatibility under the proportioning of the raw materials, and the conductive carbon black has good dispersibility in the resin. When the semi-conductive shielding material is used in a cable for preparing a semi-conductive shielding layer, the adhesive force between the semi-conductive shielding layer and an insulating layer can be effectively increased, the peel strength between the semi-conductive shielding layer and the insulating layer is improved, and the service life of the cable is prolonged.
